In some parts of the country, it's almost that time of year for ice on and in the aircraft. a couple of years ago, we in HEMS crashed a machine due to liquid water (rain) getting into the skyward facing engine air inlet - which was covered by a particulate (dirt) barrier.As temps dropped throughout the night, the liquid turned to ice. The crew launched on a flight, and the ice underneath the filter broke loose and got sucked into the turbine a short time after takeoff. The ice destroyed the engine and the aircraft did not autorotate successfully.

While installing inlet covers is a pain, if a hangar is not available, and it is going to rain on your aircraft as the temperatures drop, it may be something to consider. We at this base are going to have to go out and run the aircraft each cold morning to defrost the blades, or suffer a delay upon activation for a ground run and visual check of the rotor blades. If there is frost on the cars in the parking lot, there is frost on the blades...

About Me

I am a retired army aviator, and flew EMS helicopters from 1999 until 2015. I have flown at many different programs under traditional, community based, and hybrid models. I enjoy interacting with crewmembers as we together learn how to avoid becoming a statistic and the topic of someone else's safety brief. I teach Air Medical Resource Management, and am a member of the National EMS Pilot's Association's board of directors.
